When endodontic retreatment is needed, is using a reciprocating or rotary instrumentation system a better option? Research has produced conflicting results. To learn more, a new randomized clinical ...

In this meta-analysis, the rate of PP following canal preparation using either reciprocating or rotary instrument was assessed. The PP incidence odds ratio was 1.27, favoring rotary instruments.

Apical debris extrusion is an inherent consequence of endodontic instrumentation, where fragments of dentinal shavings, pulpal tissue and irrigants are pushed beyond the apical foramen. Although ...

Despite an abundance of studies on the topic, the mechanism of PP remains unclear. PP is usually attributed to a complex multifactorial process [11] influenced by sex (PP is reported more often by ...
